BMX Spoke Calculator

Need help figuring out what size spokes you need for your BMX wheels? Here’s a BMX Spoke Calculator that should be able to help you figure out what size spokes you need for your BMX wheels.


Our friends at Manyfest BMX over in Poland have hooked us up with a BMX tool that we think will help out a ton of BMX riders. There’s nothing worse than breaking a bunch of spokes or planning to build up a new wheel set and not knowing what size spokes you need. Luckily, this super useful BMX Spoke Calculator is available to help you figure out just what spoke size you need! This already has a ton of different hubs and rims, but as always, there are new hubs and rims becoming available all the time. This calculator offers spoke sizes for 3-cross and 4-cross spoke patterns.

    Any chance of getting the new Eclat Seismic hubs added? The front is 36h, PCD: 38mm, Flange Offset: 26.75mm. But I can’t find any info on the rear. I’d love to lace up a new set at home for more experience but I’m no math wizard to figure out spoke lengths.

      Just heard back from Elcat about the Seismic cassette:
      PCD: 45mm NDS
      PCD: 51.5 DS
      Flange (outside): 55.89mm

      Maybe this helps? I only sort of understand what I’m looking at here.

        Hey Eman,

        I’ll email them and get some other details. Essentially I need the flange diameters and the offset (Flange to center of hub) on both sides and the spoke hole size. It looks like they gave you flange diameters and the length from flange to flange.

    It would be helpful if primo’s new remix v3 was on here, also if you could look into alien nation’s black sheep rim, here it says the ERD is 190, but some other sites say 195, though I’m not sure how big of a difference that is, I feel like it should be pointed out

    So if my non-drive side is 188 mm but my drive side is 186 mm do I order 18 of each size or could I go in the middle and get 36 187 mm or just get all 188 mm or 186 mm

    I have an old primopro small flange front hub, the one that matched the very first primopro cassette the one before the mix v1, that is laced to an odyssey hazard lite rim. Need to know exactly what length the spokes are thanks!

      Hey Scott! Thank you! I have all three corrected. Those were a few that were already on the calculator when I was given it, so I assumed they were correct. That was my bad. I appreciate you letting me know!

    Hello,
    Wondering if the spoke length for the Madera Pilot front hub on the list is for the V2 or if the one listed and the V2 are the same length.
    Thanks!

    Some different measurement from profileracing website. For profile mini rear hub: drive flange diameter: 54. Non-drive flange diameter:43. Drive flange offset:28. Non-drive flange offset:33. Spoke hole diameter:2.5. Please update new measurements for them.

    Can you add the Sunday Cyclone Freecoaster to the list or let me know what size spokes I would need to fit an Odyssey Hazard Lite? I haven’t seen it on any spoke websites and I’m wondering if it’s because the hub is recent.

    • Kurt says

      Hey Korey, I have added the Sunday Cyclone freecoaster hub, along with the Odyssey Clutch V1 and V2 since all three use pretty much identical hub shells (similar internals, too). Hope this helps!

      We don’t get too into the Race world, but luckily Box is good about listing all their specs on their website. I’ve added the Box Hollow Hubs (front and rear) and Focus rims for you.

    it’s very nice you have provided this page but totally sucks since there’s no option to solve or update entered selection, rendering it completelyuseless.

      Hey Luke, we’re working on updating the list. What hub and rim are you looking for? Once we have what people need, we can find the numbers we need for it.

    Hello i have a Hub Eastern Rear 9t is white hub no idea of the model !!!

    i have a alienation 440 what size spokes do i need ??

    Reply

    • Kurt says

      We would need to know the model of the hub since all vary so much. If you can figure that out, we can get the flange diameters that we would use to calculate it.
